Just inflate and start playing. Your companion is a great source of fun for young and old alike - in the water and on land. It definitely fits in your beach bag: when folded, your water ball is small and handy. You can always take it with you to the beach and the indoor pool! It promotes both motor skills and social competencies. Since the ball is very light, almost anyone can join in the game. This makes it easy to combine therapy (e.g., training motor skills) with a social game.
